The sound of colliding black holes - and how to filter out the noise of the Universe from it

Meeting of experts at the AEI from 6 to 9 July, 2009

June 25, 2009

Scientists from all over the world are looking forward to the first direct detection of gravitational waves. With the aid of the gravitational wave astronomy that will begin once this has been achieved it will be possible to learn a great deal about the still unknown 96% of the universe. For the first time, it will be possible to listen to and observe the universe using a new frequency spectrum. In addition to high-precision detector technology, as well as theoretical and experimental basic research in numerous fields, two fields research are of particular importance in order to be able to hear and understand the sounds of the universe: numerical relativity and data analysis.

• Numerical relativity is required to accurately predict the expected gravitational wave signals.

• For gravitational wave research, new methods of data analysis are being developed to filter the tiny gravitational wave signals out of large amounts of data.

During the Numerical Relativity and Data Analysis Meeting (NRDA) 2009, around 80 international scientists from the areas of numerical relativity and data analysis will be present at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) from 6 to 9 July, 2009 to discuss the latest developments in both areas and to intensify their cooperation. For example, one question will be how to reliably filter out the sound of two colliding black holes from the clutter of noises in the universe.

We cordially invite you to participate in the conference and to engage in conversations with the scientists. For registration please contact:
